Mani Steinn is queer in a society in which the idea of homosexuality is beyond the furthest extreme. His city, Reykjavik in 1918, is homogeneous and isolated and seems entirely defenseless against the Spanish flu, which has already torn through Europe, Asia, and North America and is now lapping up on Iceland's shores. And if the flu doesn't do it, there's always the threat that war will spread all the way north. And yet the outside world has also brought Icelanders cinema!
The only witness to a shocking murder is the victim's 10-year-old daughter, Margret. The police turn to the Children's House for their expertise in childhood trauma. The manager, Freyja, doesn't much like the police - especially the detective in charge, Huldar. But she does want to help them protect Margret. And when more people die - their murders heralded by strange messages, texts, and strings of numbers - they will have to work together to crack the riddle before they become targets themselves.
